Nature Power's 23206 Bayport Solar Lamp with Pillar and Post Mounts is a stylish way to clearly illuminate your patios, decks, or walkways to provide an added measure of security for your home. The lamp has a timeless Bayport lamp post design to give it a truly authentic look. The solar lamp post features 4 ultra-white natural LED lights with high and low output setting options. When fully charged, this lamp can stay illuminated for a maximum of 10 hours. The lamp post is powered by built-in solar panels that collect sunlight and coverts it into energy used to recharge the batteries that power the lamp. Once the batteries are fully recharged, the built-in photocell sensor light sensor automatically turns the lamp post on at dusk or nightfall, and off when the sun comes up to ensure the light does not contribute to unnecessary energy usage. Though the use of solar power makes the solar lantern self-sustaining, it is important to make sure that it is setup in an area that receives ample and direct sunlight to ensure optimum performance. The solar lamp comes with a pole, column, and wall mounts to mount in any location for convenient lighting.
